Over the next year I'm going to convert my steel framed Cyclocross/commuter bike into a light touring bike. The bike accepts a wide range of racks and wheel/tires and should make a comfortable multiday tourer capable of carrying 20 to 25 lbs of gear. This weight range would include the racks, fenders, safety equipment, supplies and travel clothing. the bike & gear should weight less than 50 lbs total when fully loaded. I would like to cover 80 miles/day in 5 hours.
I'm considering gearing for the bike. I don't see the need for more than 46t as the largest chainring. I'm considering a 46t & 34t compact double with a 11-32 cassette. This would be a low cost solution.
Would this gearing allow a typical touring cyclist to climb longer 10% grades? I would like to avoid using a triple.
